TELLTALE FOR DOO RS.

SPECIFICATION forming part of Letters Patent N 0. 718,377, dated January 13, 1903. Application filed August 22,1902. Serial No. 120,633. (No model.)

To to whom it may concern:

Be it known that I, TIMOTHY OTooLE, a citizen of the United States, residing at Barberton, in the county of Summit and State of Ohio, have invented a certain new and useful Improvement in Telltales for Doors, of which the following is a complete specification.

My invention has relation to improvements in that class of devices to be applied to doors which by appropriate mechanism leave or imprint some kind of a sign or record to indicate not only the fact that the door has been moved, but practically the exact time of such movement, and it is especially designed for proprietors of places of business who intrust keys to different employees.

The object of my invention is to produce a new and improved device of the general class ject my invention consists in the peculiar and novel construction, arrangement, and combination of parts hereinafter described and then specifically pointed out in the claims, reference being had to the accompanying drawings, which form a part hereof.

Referring to the drawings, Figure l is a view of the inclosing case open and showing the operating and recording mechanism; Fig. 2, a section of the same closed at the line w as of Fig. 1; Fig. 3, a detached detail of the trip mechanism.

Referring to the figures, 1 is an inclosing metal case provided with a hinged cover 2, arranged to be secured by a look 3. WVithin this case is a sliding bolt 4:, which has a projecting end 5, beveled from each direction, so as to be pushed inward both in opening and closing the door. The main body of this bolt within the case consists of a thin bar having guide-slots 6, that slide on screws 7, secured in the back wall of the case, one only of which is shown, the other being indicated by dotted lines. The back or inner end of this bolt has an integral lug 8, beveled toward the front of the case and lowest at its rear end. This beveled lug is arranged to engage a friction-roller 9 on the end of a lever 10, pivotally mounted in the fork of a post 11, secured in the back wall of the box 1. On the opposite end of the lever 10 is pivotally mounted a latch 12, constantly held in alinement with the lever bya leaf-spring 13, which enables the latch to yield in its upward movement. The friction-roller 9 is constantly held in engagement with thelug8byadownwardlyacting spring 30. This latch is arranged to engage in its descent one end of a lever 14:, pivotally mounted in the forks of a post 15, secured in the back Wall of the box 1. The opposite end of the lever 14 is arranged to engage a flange 16 on a sliding bolt 17, the lower end of which moves in a guide 18, secured to or integral with the back wall of the case 1, and the upper end of which bears a needle 19, arranged to enter a fine hole in asplit lug 20, secured to the side wall of the case 1. A coiled spring 21 about the bolt 17 between the flange 16 and lug 2O constantly tends to draw the needle inward, and a leaf-spring 22 similarly tends to force the bolt 4 outward. Secured within the case by feet 28, so as to clear the bolt at, is a case 24, containing a clock-train adapted to run twenty-four hours; but as this clock may be of any common construction its dial only is suggested in Fig. 1 and its position indicated by dotted lines in Fig. 2. bears a cross-bar 25, having in its upper face at each end short pins or pegs 26, adapted to enter corresponding holes in a paper disk 27. This disk may be of light cardboard or bristol-board and is graduated into like spaces with the clock movement, which may be twelve or twenty-four spaces, with intermediate divisions for minutes or other desired fractions of an hour.

In operation the proprietor on closing his door places one of the disks in the machine and looks it, and by closing the door on leaving it will record it by a perforation of the The hour-hand staff of this clock card. If the door is opened during his absence, the device will record the fact, with the time it was so opened.

To prevent tampering with the machine by means of false keys, a registering device 28 of the common kind having number-disks may be placed in the box, arranged, by means of a lever 29, to be actuated at each opening of the box. It is intended in practice to manufacture large quantities of these paper indicating-disks with graduation-marks printed thereon and two openings through the disks for the insertion of the points 26, and these openings for the points will be so adjusted with reference to the numbering adjacent to the graduation-marks that when the points 26 are inserted in the openings in the disk the point immediately in alinement with the needle-hole will correspond to the correct time of the day, and by this means, should for any reason the clock run down, it can be set in this manner.

Having thus described my invention, what I claim, and desire to secure by Letters Patout, is-

1. The combination in a device of the class designated, of an inclosing case to be attached to the door, a sliding bolt mounted in said case to be normally retained in one position by a spring and to be pushed inward by encountering the jamb-plate in opening and closing the door, a time-measuring device bearing means for holding a recording-disk, a detachable recording-disk mounted to revolve with said time-measuring mechanism, a puncturing-needle arranged at a determinate position to puncture said disk and to be automatically drawn from contact therewith, interposed mechanism as a series of levers to communicate motion from said bolt to said needle, substantially as shown and described.

2. An improved telltale for doors embodying an inclosing case having a sliding bolt with the end projecting from the case to engage the jamb-plate beveled on the back and front, and the opposite end having a beveled lug, a substantially centrally pivoted lever having one end arranged to engage and be raised by said lug, and the other arranged to engage one end of a pivoted lever, the other end being arranged to engage and raise a needle-bolt, a needle-carrying bolt arranged to be operated by said last lever, and a clocktrain bearing a puncturable disk to rotate in the path of said needle, substantially as shown and described.

3. In a telltale for doors the combination with an inclosing case of. a sliding bolt having its projecting end beveled in each direction and bearing a beveled lug at the opposite end, a substantially centrally pivoted lever having at one end a friction-roller to engage the beveled end of said bolt and at the other a spring-pressed latch to engage one end of asubstantially centrally pivoted lever, a lever having one end arranged to be engaged by said latch, and the other to engage a sliding, needle-carrying bolt, a needle-carrying bolt having a needle to puncture said disk, all constructed and arranged substantially as shown and described.

at. In a telltale for doors the combination with an inclosing case of a spring-pressed, sliding bolt having a projecting end arranged to encounter and be pressed inward by encountering the jamb-plate, with a beveled lug on its opposite end, a spring-pressed lever to be engaged and tilted by such beveled end and having a spring-pressed latch at its opposite end, a pivoted lever having one end arranged to be engaged by said latch, and the other to raise a needle-carrying bolt, a needle in said bolt, a clock-train bearing a puncturable disk arranged to pass in the path of said needle and a spring to constantly draw said bolt inward, substantially as shown and described.

5. In a telltale for doors the combination with an inclosing case of a clock-train a determined shaft of which bears a cross-bar with means for holding and rotating a puncturable disk, a detachable disk mounted thereon, an inwardly-spring-pressed sliding needle-bolt bearing a needle to puncture said disk, a lever arranged to raise said needlebolt, a lever having a latch to engage the opposite end of said last-named bolt, and a spring-pressed bolt having its inner end beveled to engage the opposite end of said latchlever, and the other having a double-beveled end to project from said case, arranged to engage and be pressed inward by the jambplate in opening or closing the door, substantially as shown and described.

In testimony that I claim the above I hereunto set my hand in the presence of two subscribing witnesses.

TIMOTHY OTOOLE.

In presence of O. P. HUMPHREY, MAUDE ZWISLER.
